or 'rononro, ONTARIO, CANADA SPOOL-HOLDING DEVICE Application filed. March 6,

This invention relates to a spool holding device as described in the present specification and illustrated by the accompanying drawings.

5 An object of this invention is to so construct the spool holder that the spools can be easily fed into the device without removing it from its fixed position, without removing any of its parts and without any -1 lossof time to the operator; another object is to provide means whereby a fresh or full spool can be easily dropped or pushed into the device while it can only be taken out when empty or substantially so, the process 15 of inserting the spool into and taking it out of the device being simple and easy; another object is to build a device capable of storing each spool in its own compartment, so that the thread from any spool can be used with- 20 out interference with, or interference from, the thread of any other spool that may have been partly used, thus preventing waste of thread through tangling; another object is to build the device so that it will permit of two spools being used simultaneously (one for the machine and one for winding a bobbin) without one interfering with the other; another object is to prevent discarding of spools from which the thread has only been partly used; still another object is to design the device so that the separate magazine units can be added one above the other according as whether the capacity of the device is to be doubled, trebled, etc.; and generally, the

' objects of this invention are to provide an improved spool holder capable of storing an assortment of spools such as must be supplied to operators in factories making garments and other wearing apparel, the device being so constructed thatthe usual loss sufiered by manufacturers as a result of the pilfering of spools is reduced to a minimum, if not entirely eliminated.

complete having two superposed spool'holding units, showing parts broken away;

Figure 2 is a fragmentary perspective view of one unit, showing a typical spool holding compartment Figure 3 is a fragmentary top plan view of the top unit;

Figure' is a fragmentary bottom plan view of Figure 3.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings and particualrly to Figure 1, the device consists essentially of one or more rotatable spool holding units or magazines 10 and 11, of a cover or lid 19 bearing upon the unit 11, and of a standard 12 adapted to be secured on a table, a machine orother object and conveniently located preferably in close proximity to the operator who has to use the device. 7

The standard is shown as having a flat base 13 with screw holes 14: for fastening purposes. The stem 16 of the standard is provided with an enlarged portion or collar 15, the function of which is to support the lowermost-unit 10 which must be free to rotate thereon. The stem is made long enough to project above the, uppermost of the units, and is provided with spaced holes or slots 18A therealong to receive a suitable lock 18 the purpose of which is to secure in operative relation or assembly, the unit (or units as the case may be) and the lid 19. With a lock secured to the stem as just explained, the various units are secured one above the other forming with the lid and stand a complete unit capable of operation, and by removing the lock, the device can be dismantled or taken apart; similarly, the provision of such a lock makes for an easy assembly of the various parts of the device into a complete whole.

Each magazine is provided with a number of radially disposed pockets or spool holding compartments 20 having at the bottom stem.

a web or floor 21on which the spool rests when within its own compartment. The floor 21 is formed with inwardly extending finger or thumb slots 22 whereby to insert a finger in removing the spool when empty.

Each spool compartment is formed on the inside to a circular contour (see Figures 2 and 4) to accommodate or receive a spool, and the inside diameter (shown as (W in Figures 2 and l) is made large enough to allow the spool enough clearance to freely and easily rotate on its axis as the thread it holds is being unwound.

Each of the units 10 and 11 is open on the periphery to provide an issue or spool egress opening 22A opposite each compartment, through which the spool can be extracted or taken out of its compartment; and as one of the objects of this invention is to provide means whereby a spool cannot be extracted until about empty, the issue or opening is made to conform substantially to the vertical section of the empty spool (which is shown in dotted lines by numeral 26 in Figure 1).

lVhere two or more magazine units are used, all of the magazines except the lowermost (shown in the drawing as 10) have one compartment 28 formed without the floor 21, so that a spool may drop down through the compartment 28 to feed or fill an empty compartment in the magazine 10; the compartmeat 28 becomes in effect merely a circular passage through one magazine, and to. easily identify this passage, the outside wall opposite the compartment is painted with a vivid colour suchas red. It will be observed that all of the compartments are arranged in axes parallel with the axis of the stem 16 which passes up through a centrally arranged hole 34 in each of the magazine units and through a centrally arranged hole 35 through the lid or covering member 19.

The lid is provided with an ingress or feed opening 36 made such that while the spool can be easily fed therethrough it cannot be taken out of a compartment without removing the lid. Referring to Figure 1,. the lid is shown as having a raised. circular portion 30' around the opening 36 and recessed in by an annular groove 31 in which is soldered or otherwise secured an expansible ring 32 or neck having the lower diameter smaller than that of the spool and capable of yielding to the pressure of the spool when forced downwardly.

The upper unit 11 is preferably made with an annular ring 33 of an outside diameter slightly less than the distance 1 shown on Figure 3, one unit thus fitting into the other to complete a stable assembly.-

To facilitate the feeding of the spools into the device, it is preferable to mount the cover or lid: so that it is free. to rotate around the Operation ln assembling the device the unit 10 is mounted on the stem of the standard by lowering the unit until it rests upon the enlarged portion 15; the unit 11 is then similarly mounted and lowered until it rests upon the unit 10; the lid is next mounted on the stem and lowered until it rests upon the unit 11; the lock is next applied and the device is now complete and ready to be secured in position for its intended purpose.

In filling the lower unit 10, the lid is rotated until its opening 36 registers with the passage 28 through the unit 11, a spool forced down through the opening 36, and the unit 11 and lid rotated until the passage 28 registers or is in alignment with one of the compartments 20 in the unit 10, the spool dropping into this compartment; the lid and upper unit are rotated together until the passage28 registers with the next compartment in the unit 10 and a spool forced through 36, and so on until all the compartments in the unit 10 have been successively filled. The lid is then rotated alone until its opening 36 registers with a compartment in the unit 11, a spool forced through the opening 36, the spool dropping into the compartment; this operation is repeated until all of the compartments in the unit have been successively tilled.

lVhen a spool is empty the operator inserts afinger through the corresponding finger slot and another finger just above the spool, raises the spool and then extracts same out of its compartment. Another way of extracting an empty spool is to insert a small rod, say a pencil, through the finger slot and into the hole in the spool while grasping the lower rim of the spool with the thumb, raising'the spool, and then extracting same.
